Autism Spectrum Disorder (ASD) presents with significant heterogeneity in outcomes, particularly regarding emotional and behavioural dysregulation. Despite advances in early intervention, a substantial subset of autistic children continues to experience persistent emotional-behavioural problems (EBPs) that peak in middle childhood and contribute to caregiver burnout and reduced quality of life.
This paper addresses a specific question: Why do some autistic children develop persistent emotional dysregulation while others, with comparable cognitive and diagnostic profiles, do not? We propose a developmental systems hypothesis that integrates attachment theory, neuroimmune regulation, and caregiver-child dynamics to offer a candidate explanation.
We introduce the construct of Observer-Agent Divergence (OAD) the systematic misalignment between the behavioural meaning inferred by external observers (caregivers, clinicians) and the internal, predictive modelling priorities governing the child’s neurocognitive state. We distinguish acute OAD (normative, often repaired) from persistent or unrepaired OAD, and hypothesise that the latter functions as a relational stressor. Via established pathways linking early relational adversity to pro-inflammatory programming (elevated IL-6, CRP), persistent OAD may contribute to a self-reinforcing cycle of dysregulation, threat-hyperreactivity, and impaired social cognition in vulnerable autistic children.
We propose a clinically modest, complementary intervention architecture: The Relational Entropy Audit and Consistency in Safety Protocol. This approach trains caregivers to identify their own subtle affective signals, replace anxiety-driven interventions with disciplined, low-arousal environmental stability, and implement explicit acceptance signaling. The protocol is designed to complement existing developmental and behavioural interventions by targeting the relational environment as a modifiable determinant of inflammatory and neural regulation.
This paper presents a conceptual synthesis rather than an empirical study; no primary participant sample was recruited. The hypothesis was developed through a targeted narrative synthesis of literature across attachment theory, predictive processing, and neuroimmunology, selected for direct relevance to caregiver-child affective signaling and inflammatory pathways in ASD (see Methods: Conceptual Synthesis Approach).
We outline specific, testable predictions including biomarker validation, neuroimaging studies, longitudinal mediation models, and pilot randomised controlled trials that would substantiate or falsify the hypothesis.
We recommend that biomarker validation (Prediction 1) and open-label feasibility piloting of the Consistency in Safety Protocol precede any randomised controlled trial, and we identify longitudinal mediation and neuroimaging studies as priority areas for future research (See Recommendations and Priorities for Future Research).
If validated, this framework would reframe a subset of ASD-related dysregulation not as an intrinsic deficit, but as an environmentally-modulated signal of relational entropy, demanding not suppression of the child’s alarm signals, but disciplined recalibration of the relational field.
